Adjustable tapered washer

Abstract

In one embodiment, a washer assembly, comprising: plural washers adjacent each other, each having a tab and a tapered body of a defined angle, wherein relative adjustment of the tabs corresponds to a composite angle range from zero to twice the defined angle.

1 . A washer assembly, comprising:
 plural washers adjacent each other, each having a tab and a tapered body of a defined angle, wherein relative adjustment of the tabs corresponds to a composite angle range from zero to twice the defined angle.   
     
     
         2 . The washer assembly of  claim 1 , wherein each of the tapered bodies comprise a central opening. 
     
     
         3 . The washer assembly of  claim 1 , wherein a composite angle of zero corresponds to one of the tabs one hundred eighty degrees apart from the other of the tabs. 
     
     
         4 . The washer assembly of  claim 1 , wherein the composite angle of twice the defined angle corresponds to each of the tabs exactly aligned and adjacent each other. 
     
     
         5 . The washer assembly of  claim 1 , wherein a quantity of the plural washers is two. 
     
     
         6 . The washer assembly of  claim 1 , wherein a quantity of the plural washers is more than two. 
     
     
         7 . The washer assembly of  claim 1 , wherein each of the tabs is un-tapered. 
     
     
         8 . The washer assembly of claim, wherein each of the plural washers are comprised of stamped or coined metal. 
     
     
         9 . The washer assembly of  claim 1 , wherein each of the plural washers comprises any one of a plurality of body geometries. 
     
     
         10 . A system, comprising:
 a chassis comprising an opening;   a shaft inserted through the opening and operably coupled to the chassis;   a bushing cylindrically surrounding the shaft;   a pulley mounted to the bushing and the shaft; and   a washer assembly according to any preceding claim arranged between the bushing and the chassis, the washer assembly serving to compensate for misalignment of the pulley relative to the chassis that is present without the washer assembly.   
     
     
         11 . The system of  claim 10 , further comprising a securing member coupled to the shaft and that is adjustable to clamp the plural washers between the bushing and the chassis. 
     
     
         12 . The system of  claim 10 , wherein the shaft comprises an arm pivot shaft operably coupled to the pulley, the pulley comprising a tensioner pulley.
